Classroom Crisis

A-TEC, led by brilliant engineer Kaito Sera, is a classroom of Kirishina Corporation's greatest minds leading aerospace development in Martian colony Fourth Tokyo. They are excitedly awaiting the arrival of their newest member. However, it quickly becomes apparent that the transfer student is anything but ordinary—Nagisa Kiryuu, the recently appointed A-TEC chief and the CEO of the company's younger brother, is sent to terminate the program. While Nagisa works his way up the corporate ladder in pursuit of his own goals, Kaito and his students struggle to create a replacement for their most potent rocket, the X-2, in order to maintain the classroom. Despite this, their individual conflicts quickly make clear that there is a lot more going on in Kirishina Corporation than initially appears.
